To'all whom it may concern:

Be it known that I, JOHN F. OCoNNoR, a citizen of the United States,residin 'in Chicago, in the county .of Cook and tate of Illinois, haveinvented a new andusefill Improvement in Draft-Rigging for Ra1lway-Cars7of which the following is a speci fcation. This application is adivision of my ogiinal application No. 421,438, filed March 16th, 1908.

My inventio-n relates to draft gears or rigging for railway cars.

The object of my invention is to provlde adraft rigging ofaaconstruction adapted for-use on cars having-a single center sill,

and it consists in the means- I employ to practically vcombinewith andapply to a single center sill car the draft rigging.

The preferred embodiment of the invention is shown and described in theaccom-.I panying drawing forming aA part of lthis specification.

In said drawing, Figure 1 is a side elevation,A partly in central,longitudinal see-A tion, of a single center sil1` draft riggingembodying my invention. Fig. 2 is av plan view, partly in cent-ral,longitlidinahhorizontal section. Fig. 3 is a cross section online"3.3'of Fig. 1. Fig. 4 shows a modified construction of the yoke.And Fig. 5 is a detail view of the connectingV block between the twoseparate piece limbs of tlieyoke shown in Fig. 4.

In the drawing, A represents the center siil of a car of the kind havinga single center sill directlyV in line with the drawbar B.

C is a horizontally disposed draw-bar yoke connected with the draw-bar Bby a( flat, horizontally extending key El The twomembers or limbs of theyoke C are prefer# ably formed in one integral piece, anda` iller blockD is also preferably inserted at the bent rear end of the yoke, thesamebeing shaped to fit the rounded'corners thereof.

F and F1 are the front and rear followers and F2 F 3 intermediatefollowers extending uprightly through the horizontally disposedvdraw-bar yoke C. V

are the uppe and' lower stop members or stop castings, each preferablycomprisingtwosepar-ate' members or castings to fit against and securelyriveted to the upright web a of' the single center sillV and to theupper and lower flanges a* and a2 thereof as will be readily understoodfrom Figs. l, 2 and 3 of the drawing. Each of thelstop members orcastings G is furnished with stops or shoulders g g1 g2 g3 g4'g5 g g7fertile followers F F1 F2 F3 to abut against, tliestops or shoulders g1g2 g* g7 being limiting stops to limit `the compression of thetandemarranged cushioning springs H H1 of the draft rigging.

The'central upright web a of the single center sill A has a'l central,longitudinally extending slot, recess, pocket or cut ont portion,A1, toreceive the draw-bar, followers and springs, said slot or cut outportion exlas will be readily understood from Fig. l

ofthe drawing.

-.. Thedraw-bar yoke C is furnished with an intermediate abutment blockC1 between the two intermediate followers F 2 F3 to cause the. saidintermediate followers to move alternately with the draNv-bar in pullingor .bufiing, said abutment block being secured to the draft yoke C byhorizontal connections or'bolts C2 which extend transverselyl throughthe abutment block C1 and the limbs of the draft yoke C. The draw-baryoke at the front end of its'two limbs is. preferably furnishedwithbends or folds C3, the ends of which may abut against the front followerF, said folded ends of the draft yoke giving" an extending bearingcontactbetween the draft yoke and the hori zontal key E by which thedraft .yokeis connected to the' draw-bar.

the' slot lor opening A1 in the vertically dis- 'posed4 web@l oft-hesingle center sill -A for the draw-bar B to project through and toVpermit the draw-bar to swing laterally as required. A-nd the frontplate or carryiron A3, which lits outside of and in front of the endsill A2, is provided with an inwardly or rearwardly projecting flange a3for-the Adraw-bar to ride upon and give an extended bearing surfacetherefor. i

Tie-plates or castings K K are'provided, one on each side of theccnter-silLA,l the of a channel form in cross section adaptedbolts Kxhaving threaded/nuts K2. These same being removably secured in place bytendingthe full length of the draft rigging, A

y .The front end sill A2 of the car is provldedwitha central'opening A*in line with' neled stop members GG limbs Cf of the yoke which aremadea'n sep- -tally disposed draw-liar yoke connected to 'and front,rear and iiilerniediatcv followers` upright tie-plates K are eachfurnished with a guide channelu K3 to receive the two limbs or membersof the draw-bar yoke C, which, fit one on each side of the uprightfollowers' F F1 F2 F3. The followers F F1 F 2 Fs rest and reciprocate attheir lower edges upon the horizontal flanges g8 of the lower stop,member G, said flanges thus affording a smooth, wide and extendedbearing for theV followers to rest and reciprocate upon. Tfiecorresponding horizontal flanges g8 of the upper stop member G alsoserve as a wide or extended guide or chafing plate for the upper edgesof the followers. The chanseciired to the upper and lower bifurcatedportions A5 A6 of the single center-sill' A, above and below the centralslot or draft rigging pocket A1 formed therein, also serve asreinforcements to stiffen and strengthen the center-sill and tocompensate for the weakening thereof by the central, longitudinal slotor eut out portion A1. The central web a, of the single center sill A ispreferably provided with upwardly and downwardly projecting integralstop shouldersI or tongues a4 registering with the several stops of thestop members G G so that these unciit-out or projecting shouldersa ofthe web (i may serve as fiir ther stops or as reinforcements for thestops g g1 g2 g3 g4 g5 g6 g7 of the stop members G.
